Abstract

1462876 Knee joints CHAS F THACKRAY Ltd 29 April 1974 [17 May 1973] 23493/ 73 Heading A5R An endoprosthetic knee joint comprises a femoral portion, 22, 23 Figure 7, and a tibial portion, 25, 26, the femoral portion comprising two femoral implants, Figure 1, each being designed for implantation into one of the femoral condyles 20, 21 and having a bearing surface 1 shaped as a segment of a right circular cylinder, and the tibial portion, being designed for implantation into the upper end of the tibia and presenting, for each femoral implant, a planar upper surface 10, Figure 3, on which the bearing surface of the femoral implant will bear. The femoral implant is formed from a plastics material such as high density polyethylene, and has a substantially frusto-conical cross-section with converging side surfaces 3 (4), Figure 2 (not shown), each formed with an arcuate groove 5 (6). These grooves and a transverse hole 7 are for keying to the fixing cement, which may be an acrylic. The ends of the implant 8, 9 are convex. The chord joining the extremities of the arc 1 is of length 1“"-2". The tibial portion comprises two tibial plateaux, Figure 3, which may be linked by a bridging bar, which may be integrally formed with the two plateaux, or may subsequently be welded thereto. Each plateau comprises a cap for keying to the upper end of the tibia. The plateaux may be made of stainless steel, or alternatively of chrome/cobalt or other metallic alloy, or some other material not degradable within the body. Each tibial plateau has a planar semi-circular upper surface 10 with a flange 11 containing a slot 12 extending from the straight edge, and a lip 13, which may be chamfered (14), Figure 6 (not shown), around the arcuate edge. Flange 11 and lip 13 act to retain cement, and slot 12 assists keying to the cement. The lip 13 may extend as far as the flange on each side, or may be cut away (15, 16) for ease of manufacture, thus allowing for the escape of cement during fixing. The materials used respectively for the femoral and tibial portions may be interchanged; a portion made of polyethylene may be formed by machining, forging, sintering or moulding. A tibial portion comprises right-handed (31) and left-handed (30) plateaux, Figure 8 (not shown), which are mirror images of each other, but lack symmetry as regards the shapes of the ends of the lip (32) and of the flange (36).
